Borrowing against shares offers liquidity but creates high-stakes exposure to market volatility. With new RBI regulations effective July 1, 2026, setting a ₹1 crore individual exposure limit and specific Loan-to-Value (LTV) caps, investors must understand how margin calls and forced liquidation can impact their portfolio during market downturns.
A Loan Against Shares (LAS) allows investors to unlock liquidity from their existing stock and mutual fund portfolios without selling the assets. While this provides immediate cash for personal or business needs, it effectively binds the borrower’s financial health to market performance. Since July 1, 2026, the Reserve Bank of India (RBI) has implemented a tightened regulatory framework, aiming to standardize these products and curb excessive risk-taking.
Understanding the New RBI Regulatory Framework
The central bank’s recent norms have brought more structure to this segment. The most significant update is a system-wide exposure cap of ₹1 crore per individual borrower. This ensures that no single investor can use pledged securities to take on excessive debt. Furthermore, the RBI has standardized Loan-to-Value (LTV) ratios to provide safety buffers for lenders. For listed shares, the LTV ceiling is capped at 60%, meaning that for every ₹10 lakh worth of pledged shares, the maximum loan amount is ₹6 lakh. Other assets have different tiers: equity mutual funds, REITs, and InvITs have an LTV cap of 75%, while debt mutual funds and top-rated bonds allow for up to 85% borrowing. Additionally, loans specifically intended for stock market or IPO investments are strictly capped at ₹25 lakh.
The Mechanics of Margin Calls and Liquidation
The primary risk for any borrower in this arrangement is market volatility. Because the loan is secured by equity, its value is tied to current share prices. If a sharp market correction occurs, the value of the pledged collateral drops, potentially causing the LTV to exceed the 60% threshold. When this happens, lenders issue a margin call, requiring the borrower to either pledge additional securities or pay down the loan principal to restore the required cover. Under the current regulatory guidelines, borrowers typically have 7 working days to meet these requirements. Failure to act within this window gives the lender the legal authority to trigger a forced liquidation of the pledged shares to recover the outstanding dues.
Tax and Financial Implications
It is important for investors to note that pledging shares does not immediately trigger capital gains tax, as the transaction is not viewed as a sale. However, the situation changes significantly if a default occurs. If the lender sells the shares, the transaction is treated as a taxable capital asset transfer, which could result in unexpected tax liabilities for the borrower. Furthermore, the risk is asymmetrical: if the lender sells shares to recover the loan and the proceeds fall short of the total debt, the borrower remains legally liable for the remaining balance. Additionally, the borrower loses the benefit of any future price appreciation that might occur after the forced sale, as ownership has effectively been transferred to the lender for the purpose of debt recovery.
For investors using this facility, the most critical monitorable is the LTV buffer. Maintaining a portfolio well above the minimum required collateral helps avoid forced sales during periods of temporary market stress. Keeping documentation organized for tax filing is also essential, as the burden of proof for the nature of the transaction rests with the asset holder.
